    v, err := NewSwaggerValidator("https://raw.githubusercontent.com/OpenBankingUK/read-write-api-specs/v3.1.0/dist/account-info-swagger.json")
    if err != nil {
        panic(err)
    }
    
    failures, err := v.Validate(r)

        panic(err)
    }

    fmt.Printf("Validation failures found:\n%v", failures)    
}
